Thru personal experience, Colin Wilson discovered that human beings consist of a ladder or hierarchy of selves, whose upper members may be called upon at will for personal transformation & deep knowledge. His new-found knowledge spurred him to write Mysteries: An Investigation into the Occult, the Paranormal & the Supernaturalan attempt to apply his theory to all paranormal phenomena, from precognition to Uri Geller's spoon bending. He presents detailed studies of hauntings, possession & demonic hypnosis, as well as magic, the Kabbalah & astrology. At the heart of his work is a fascinating discussion of the Great Secret of the alchemists, which he sees as the key to the mystery of the ladder of selves.
